Everything is cosmos:

the stones, the mountains, the trees, the flowers, the herbs, the stars ...

all nature, and non-nature,

the artificial, and all human, material and spiritual products,

and space and time.

- Eihei Dogen -

... and we, I add, we too are cosmos, we are permeated by the cosmos and we permeate the cosmos. There is no distance, there is no discontinuity between us and the stars, nebulae, comets and black holes. The fundamental elements that make up the entire cosmos are the same elements that make up our life and our physical and spiritual body (hydrogen, nitrogen, carbon, sulfur). Elementary.
